Trubisky has missed two games with a shoulder injury, but practiced fully all week and is not listed in the status section of Friday’s injury report.

Said Bears head coach Matt Nagy: “He put together three really good days at practice. The main thing for us was just seeing conditioning-wise if he can hold up and he did.”

In Kansas City, it appears that Baltimore Ravens rookie quarterback Lamar Jackson will make his fourth consecutive start even though Joe Flacco practiced fully Friday. Flacco, who has been out because of a right hip injury, was limited on Wednesday and Thursday. Head coach John Harbaugh acknowledged that Flacco has made good progress, but that he hasn’t yet been cleared medically to play.

If he receives that clearance and Jackson remains the starter this week, Harbaugh will decide between Flacco and Robert Griffin III as the backup.

In Buffalo, it is expected that rookie quarterback Sam Darnold will return as the starter after missing three games because of a foot injury. Darnold was a full participant in practice all week. Head coach Todd Bowles said an official announcement won’t be made until game day and said, “Between him and Josh [McCown], they both had good weeks.”

Several teams will be without their main running back: Melvin Gordon, Chargers; James Conner, Steelers; Kerryon Johnson, Lions; Matt Breida, 49ers.
